PUMPING APPARATUS.

Application filed October 3, 1928. Serial No. 666,282.

To all whom it may concern: 7

Be it known that I, CLARENCE WARNER, a citizen of the United States of America, residing at Dayton, county of Montgomery, State of Ohio, have invented certain new and useful Improvements in Pumping Apparatus, of which the following is a full, clear, and exact description.

This invention relates to pumping apparatus, and has among its objects the provision of a pump driving mechanism that will be simple and compact and may be readily disassembled for repairs or replacement of parts.

Another object of the present invention is to provide for the lubrication of the mechanism with the minimum liability of mixing the lubricant with the fluid being pumped.

Other and further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred embodiment of one form of the present invention is clearly shown.

In the drawings:

Fig. l is a vertical sectional view of a pump driving mechanism embodying the present invention.

Fig. 2 is a sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a view in elevation of the pump driving mechanism, looking in the direction of the arrow A in Fig. 1, a portion of the motor being broken away.

Fig. 4 is a diagrammatic View, looking in the direction of the arrow B in Fig. 1, showing various positions of the driving mechanism.

.Fig. 5 is a fragmentary sectional view taken on the line 5-5 of Fig. 1'.

Referring to the drawings, a gear housing is secured to a base 21 by bolts 22. Housing 20 is provided with an annular flange 23 providing a relatively wide bearing surface. An end cover 24 provides a closure for an opening 25 in gear housing 20, and is secured thereto by bolts 26. The cover 24 also provides a bearing 27. Cover 28 which encloses bearing 27, is secured to cover 24 by bolts 29. Thus the housing20 find cover 24 constitute a lubricant chamtion 62 of A casing 35 which is secured to the housing 20 by bolts 36, is provided with an opening 37. This casing 35 also provides a lubricant chamber 38, having communication with lubricant chamber through passage 39 and through the interior of flange 23. A casing 40 which is secured to the wall 41 of casing by bolts 42 and nuts 43, provides for the passage therethrough of a recip eating pump rod 45. A removable 'cover 46, secured to casing and casing 35 by screws 47, provides a closure for the upper end of pump rod 45 and a connecting arm 48 which fits over the threaded end of pump rod 45. Nuts 49 and 50 permit of adjustarm 48 with respect Arm 48 extends downwardly through the opening 37 in casing 35.-

n electric motor 50 is attached .to' one end of the gear casing 20 and is provided with a motor shaft 51 which extends through casing 20, and is journalled in bearings (not shown) carried by casing 20.

A flywheel 52 is suitably secured to motorshaft 51 at the opposite end of casing 20, and cover 53, secured to casing 20 by bolts 54, provides a closure for the flywheel 52. A Worm 55 is provided on motor shaft 51 substantially centrally of casing 20.

internal gear is secured to the inner surface of' casing 20 by bolts 61 and is arranged concentric with the opening provided by annular flange 23. Reduced porgear 60 is adapted to fit within the recessed portion 63 of casing 20, so that the gear 60 may be easily located in proper position with respect to the opening provided by annular flange 23. A rotatable member 65, provided with a disc flange 6 6, is journalled in the relatively 67 provided by an annular flange 23. R0- tatable member is secured to a shaft 70 as an axis by key 71. Shaft 70 is provided with a shoulder 72 which engages a recess 73 in member 65. A sleeve or journal member 74 having a reduced portion 75, is also secured to shaft 70 by key 71. Bearing sleeve 76 fits loosely over the reduced portion of sleeve 74, and is threaded as at 7 7 for engagement with of bearing 27. A nut 78 also engages the threaded portion 77 to prevent accidental turning of sleeve 76. A washer 79. and a the tapped outer end wide bearing nut 80 engaging the threaded end of shaft 70 limit endwise movement of sleeve 7 4 and shaft 70 withrespect to the sleeve 7 6. Member 65 providesbearings 80 an eccentric with respect to shaft 70 and Which are spaced apart by opening 82.- A crank shaft 83, having a crank arm 84, is'journalled in bearings 80 and 81, and is held in .position by washer 85 and nut 86 en agingt'he threaded end of crank shaft 83. gear 90, the diameter of which is equal to the radius of internal key 91 and 'meshes with turningthe sleeve. The adjusted position of sleeve .76 is maintained by connecting arm .30

lock nut 7 8.

A crank pin 95 is carried by crank arm 84; and is adapted, upon rotation of crank shaft 83 and shaft 70, as before described, to be reciprocated within the lubricant chamber 38. Crank pin 95 is connected with 48 by a universal connection shown in Fig. 5, the arm 48 being notched at its lower end at 96 and receiving a member 97 which is pivotally held in notch 96 by a bolt 98. Member 97 supports a bearing tions of the 99 which receives the crank pin 95. A cot ter pin 1'00 and a washer 101 hold the member 97 and bearing 99 in position on the diagrammatically two posigearing for transmitting straight line motion to the pump rod and arm 48. In this figure, the circle represents the gear 60 and the circle 90 the 95 in Fig. 4. Since gear 90 which meshes with the gear 60. The

'full'line-position of circle 90 represents the 7 lowest vertical position of the gear '90 as it rolls Within the internal gear 60.- The rotatable' member is represented as an arm 65 in Fig. 4 which rotates about-the 1 point rep-resenting the shaft 70, and carries with it the crank shaft 83 represented by circle 83 in Fig. 4. Line 84 represents the crank 84 and connects the crank shaft 83 withthe crank pin represented by circle the pitch diameter of gear 90 is equal to the pitch radius of gear 60, it follows that the path of movement of any point on-the pitch circumference of gear 90 will be astraight line as the gear 0d 90 rolls within the gear 60. Since the length of crank 84 is equal to the pitch ra' dius of gear 90, it follows that the crank pin 95 will move in a straight line. As shown in Fig. 4, the axis of pin 95 'coincides with the point of contact of the pitch circles of gears 90 and 60 when gear 90 is in the lowest line motion position. Therefore the-path of movement of the axis of crank pin 95 will be in a vertical line passing through the axis of gear 60 and shaft 70. Since the crank moves in a straight line as its crank shaft 83 moves in an'orbital path indicated by the dotted circle 183 in Fig-4, it follows that the arm 48' connecting thecrank pin 95 with the pump rod 45 will have simply straight and will not be oscillated. Therefore no bearing requiring lubrication is necessary in the connection between the connecting arm 48 and the pump rod 45. It follows therefore that the bearings requiring lubrication can be all located within relatively limited boundaries, thereby facilitating the lubrication of such bearings and permitting the use of simple means for the pump rod and to the well through which 'the pump rod extends.-

The mechanism which imparts to the crank pin 95 a straight line motion from the rotating shaft 70, is of such a nature as to cause a force to'be applied to the crank pin in either direction of its motion which is relatively great at the end of its travel up or down as compared with intermediate portions of its travel. In other words, a toggle'action is produced upon the crank pin 95. This action is shown diagrammatically in Fig. 4. Assume that .the direction of retation of the rotatable member 65 is clockwise, as indicated by the arrow G in Fig. 4. As the crank pin ,95 moves vertically upwardly, the rotatable member indicated by .;7O thereby causing the toggle link 84 to rotate about the axis 83. As already explained, the movement of the crank pin 95 at the end of link 84 is confined to straight line movement. Since the distance moved by the point 83 topoint 83 is much greater than the distance moved by pin 95 to point 95, it follows that the force applied at the pin 95 is greater than the force applied at the point 83 at the beginning of upward movement of pin 95. This action is advantageous in pumping apparatus since relatively great force is required at the beginning of each stroke of the pump rod in order to overcome inertia, weight of the moving parts and the water lifted by the pump.

It will be apparent that the lower edges of the bearing 99, which is reciprocated in the lubricant chamber 38, is below the level of the opening 37 at all times, so that when pin 95 as a unit from the gear ing the bolts 36 or casing 40 may be re-' moved separately by loosening nuts 43. To'

the member is rotated, the bearings 80 and 81 will dip into the lubricant and thus lubricate the crank shaft 83. Gear 90 will be lubricated by lubricant entering the cored opening 82. The lower edge of bearing 67 is submerged in lubricant and the worm gear 93 carries lubricant to the worm 5l,

Thecasings 40 and 41 may be removed casing 20 by removremove the gearing fromthe gear housing 20, the cotter pin 100 and washer 101 are removed, and the crank arm 84 is turned to a position so that it will clear the flanged portion 23 of housing 20. Then the screws 26 are removed. It is then possible to remove through opening 25 of gear housing 20, the cover 24, the shaft 70, member 65 and other parts carried thereby, all in assembled relation.

While the form of mechanism herein shown and described constitutes a preferred one form of the invention,
